There are some cop spooling machines in which the winding on all thespindles or at any rate on a group of spindles is started and stoppedsimultaneously, in the entire machine; or the group of spindles isstopped in order to remove the cops and put on new tubes. done by hand,and necessitates a relatively long stoppage of the spindles, withconsequentreduction of efiiciency as regards the output or the machine.In connection with ring spinning, certain devices have been-contrivedfor the purpose of taking off the full spools or cops and putting on thetubes in groups, the full spools being lifted by means of forks fittedwith pins, or 'by grippers. The disadvantage of these arrangements isthat in some respects they interfere with the operation of the machine,as they. are more or less in the way of the operator, even if duringnormal working they are removed from close proximity to the spindles.This renders it almost wholly impracticable to apply them to spoolingmachines, owing to the greater strain on the thread, which causes farmore breakages of thread and other troubles in winding, which must berectified by the operator during the working of the spindles.

The importance of simultaneous removal, of

Lil

finished cops followed by a simultaneous mechan- Gil ' 7 been proposedto use a. conveyor band which can be raised andlowered to lift the emptytwist rollers into the plane of the retractable spooling spindles (whichcan also be drawn) to take up the released full rolls of twist and toplace the empty ones between the spindles and the centres. A device ofthis kind, owing to the trouble'and expense of fitting it up, cannot beused in cop spooling machines, and also obstructs the view of theprocess of spooling.

The object of our invention is to make it DO sible to effectsimultaneous winding of cops and exchange of cops for empty tubes, inthe whole bank of spindles, or any group of spindles, however large,without incurring the disadvantages described above. For this purpose wearrange the cop handling unit outside the area of arrival of the tread,and we provide for relative movement of this unit and the spindles. Withthe I spindles stationary, the cop handling unit may be This hashitherto been movable both transversely of the axis of the spindles andalso in the direction of the spindle axis, or it may move only in theaxial direction. In the case of axially movable spindles the-cophandling unit may be movable transversely of the spindles, and inthecase of cop spools which are inserted between the spindles and a backcentre, the unit is movable transversely of the spools and also axially.I

Several examples of apparatus according to the invention are shown inthe annexed drawings.

Figs. 1 to lO'illustrate diagrammatically that form of the device inwhich the spindles are stationary and the unit X, which serves anydesired number of spindles, is movable both transversely of the spindleaxis and also in the direction of the spindles.

In Figs. 1 and 2, I is the winding spindle, F the thread, 2 the frictionwheel seated thereon, which is driven by friction disc 3 mounted onshaft 4. The shaft 4 isdriven in the usual way. 5 are the thread guides,which are mounted on a bar 6 in common with all the other thread guidesof one side of the machine, or for a group of spindles. The bar 5 isactuated by racks l and a pinion 8, the pinion being fixed to a shaft 9.On the same shaft 9 there is fixed a disc II], with a chain I I engaginga portion thereof. The chain II at its upper end also engages with adisc I2, around a portion of the latter. The disc I2 is fixed to a shaftl3. The latter is mounted on a lever I5 pivoted at I4. The lever I5carries a pin with a roller [6. This roller I6 is moved by aheart-shaped cam I! on a shaft I8. The shaft I8 is driven by a gearwheel I9 and gear wheels 20 and 2i. The gear wheel 2i is mounted on thedriving shaft 4. The gear wheel I9 is freely rotatable on its shaft I8,but is restrained from lateral displacement and can be coupled with acollar 22, which is slidable on the shaft I8, to which it is splined.While this coupling 22 is out of engagement the shaft I8 with its heartcam I1, and consequently the entire mechanism II, I0, 9, 8, l and 6 isstopped, although the top spindles I can continue to rotate. The feedmovement of the thread guide 5 takes place in the following way:

On the shaft I3 there is fixed a worm wheel 24, with which engages aworm 25 having its bearing shaft on the lever I5. To the same shaft isfixed a ratchet wheel 26, which is rotated stepwise by a double armedlever 21 and pawl 28, backward rotation being prevented by pawl 29. Oneach stroke of the lever I5 the lower arm of the lever 21 strikes anadjustable screw 30, so that the swing of the lever can be regulated byadjustment of the screw, and this regulates the angle through which theratchet wheel is rotated. The chain II is wound on to the disc l2 andoff the disc Ill, and at the same time the shaft 9 with gear wheels 8 isrotated and the racks I with the thread guides 5 are shifted. In orderto keep the chain II taut there is a disc 3| fixed to the shaft 9, witha chain 32 carrying weight 33 attached to its rim. The weight 33 notonly keeps the chain ll taut but also effects the backward movement ofthe thread guide when pawls 28 and 29 are disengaged and ratchet wheel26 is rotated backward by its handle 26a.

The cop handling unit, which is designated as a whole by the referencecharacter X in the various figures, is shown in Figures 3 to 10.

The unit X may form a single rigid frame for a plurality of spindles,the longitudinal walls 340. and 3 b of the said frame being connected bytransverse walls 35.' The longitudinal walls are further connected witheach other by troughs 36 in the manner of a grating. In these troughsthe empty cop tubes 31 are placed ready for slipping onto the spindles.Centrally between two troughs 3G, notches 38 are provided at the upperedge of the longitudinal wall 34?), which, for the purposes of strippingoff the full cops'Bla from their spindles. I engage each bare spindlebehind the foot of the cop. The unit X is arranged below the plane ofthe spindle axes. It rests on rollers 39a and 39?), which are mounted onlevers 48a and 40b. The levers Ma and 40b rotate about shafts Ala andE-lb. To the shaft lla is fixeda hand lever 42 (Fig. 2). By means ofthis lever and rods 33, chains, or the like, the unit X can be movedfrom the position of rest shown in Fig. 3 to the position shown in Figs.5-10. The shafts lla and ill) are mounted in the machine frame Y at Maand 44b (Fig. 1) and are in the form of toothed racks towards theinterior of the machine.

The shaft 4Ia is formed as a toothed shaft at its rear (Fig. 5) andengages with a pinion 45 mounted on a shaft 46. This shaft can berotated. by a hand wheel 41 (Figs. 1 and 2), and in this way the body Xcan be shifted not only vertically but also horizontally, this lattermovement being for the purpose of shifting it into the position shown inFigs. 7 and 8, from the position shown in Figs. 5 and 6, after it hasreceived the cops or bobbin tubes. In order to be able to shift the bodyX lengthwise of the machine it slides with its transverse walls 35 onpins 58a and 48b, for which purpose the transverse walls have a slot 49,of angular form, the vertical part of which'serves for the upwardmovement of the body X, while the horizontal part allows of the forwardmovement. The longitudinal movement of the part X on the pins 480 and48b, is limited by suitable stops 50a and 50b. The longitudinal movementof the part X on the rollers 39a and 3% may be effected by hand or bylever mechanism not shown.

The manner of operation is as follows:

In Figs. 3 and 4 the cops 31a on the group of spindles have just beencompleted. The end thread F is wound around the cop in a steep spiral bya rapid return movement of the thread 4 guide in the manner previouslydescribed; on the bare spindle I a few turns have been run at la, sothat the thread is held firmly at this point and the cop is ready forstripping off. The part X is in its position of rest beneath thespindle. In the trough 36, a cop tube 31, ready for slipping on to thespindle, is indicated by broken lines.

The operator then raises the unit X vertically upward by the aid of thelever 42, so that the notches 38 in the rear longitudinal wall 34bengage the spindles l behind the cops.

As shown in Figs. 7 and 8 the part X has already been shifted forwardout of proximity to the spindles by means of the handwheel 41, pinion45, and the rack portion of shaft dla (Figs. 1 and 2); during thisoperation all the cops 31a have been stripped off and have dropped intothe box 52 at the bottom of the unit X, from which they can be taken outby hand.

After the cop has been drawn off the spindle, the part X is moved to theextent of about half the pitch of the spindles, see Figs. 8'and 9, sothat the empty cop tubes 3'! are in line with the spindles.

"n In Figs. 9 and 10 the part X is moved by wheel iii)" 42, returned toits lower position. The thread guides are now, by means of the ratchetwheel or hand wheel 26 (Figs. 1 and 2), brought back to the startingposition for the new winding operation, and the rotation of the spindlesI is started at the same time by throwing the driving belt I60 by meansof belt shifter I6I from the idle pulley I62 to the fixed pulley I63,whereby the thread fixed upon part Ia of the spindle winds around thebare cop tube to begin the winding operation.

- When the cops are fully wound the process above described is repeated.

Figs. 11 to 16 illustrate an example in which the spindles are axiallymovable. Consequently the unit need not be movable in the direction ofthe spindle axis, its movement transversely of the spindles beingsuflicient.

, The cop handling unit does not in this case differ in its essentialparts from the other ex- 99 in the trough 52 is shown in Figs. 19 and20.

The relatively long part of the shaft I03 between the gearings I04 istoothed.

To the trough 52 two holders I05 are fixed, which serve as bearings fora shaft I06. On this shaft, between the holders I05, there is a roller99a, which serves to drive conveyor 99. At one end of the shaft I06there is a pinion I00, which is in constant mesh with the toothed partof the shaft I03, and can move along that part together with the trough52 and the conveyor 99. From this it is clear that the endless conveyorcan be set in motion in any position of the device X. The movement forthe conveyor with the full cops takes place during the working of themachine.

The drive of the spindles can in this case be by cords or bands 85extending between driving pill-- leys 3c and the driven pulleys 2c. Thepulleys 2c are fixed to sleeves 2d having square bores in which spindlesI can slide longitudinally without being permitted to turn relatively tothe sleeve. The spindles furthermore are rotatably mounted in the anglebar carried by the racks c. The movement to and fro of the-spindles l,is effected by a pinion 45c meshing with a rack 460.

When the cops are ready, the cop handling unit is lifted by means ofhandle lever 42 and the arms 40a, 4012 from the position .shown in Fig.11 to that shown in Fig. 12, and subsequently the spindles I areretracted, so that the spools 31a are released by the action ofstripping faces 30 and fall into the trough 52. When this has been donethe cop handling unit is moved to the extent of half the distancebetween two spindles, so that a tube is placed in front of each spindle,as shown by broken lines in Figs. 11 and 13. The spindles are then movedforward from the position shown in Fig. 12 to that shown in Fig. 13, andpick up the tubes, whereupon the cop handling unit is moved back to theposition shown in Fig. 14, by the manipulation of handle lever 42. Inthis case one longitudinal wall 34b of the part X may 5 be provided, atthe point where its notches 38 engage over the spindles, with knives 84,the object of which is to cut the thread before the cops are strippedoff. This cutting is effected by turning the spindle I, as this conveysthe thread tom wards the cutting edge of the knife 84.

In Figs. 15 and 16 this part of the device is shown to a larger scale.

Theexample shown in Figs. 17 to 20 deals with the case in which thedevice X is movable only 15 in the direction of the spindle axis. Thecontainer 52 with the conveyor 99 and the axial shift by rack Ma andpinion 45 are the same as in the embodiments shown in Figs. 1-16. Thepart X, however, carries a table 90, with recesses for 20 receiving thetubes 31, which rest against a rail 90a. On the bottom face of the tablethere are bars 93 (in this example one for each spindle) withlongitudinal slots 93b for engaging over guides 9 I, 92 fixed to thetable, so as to allow movement in the direction of the spindle axis. Onthe end facing the spindle each bar has a part 93a engaging behind thespool, and a pin 94 behind which a hook lever 96 engages. All the hooklevers 96 of those spindle groups which belong together, or all thespindles on one side of the machine, are mounted on a shaft 95, whichcan be rotated through a definite angle by a hand lever 91. When thewinding of the spool 31a is completed, and after release of all the bars93 35 by the movement of the lever 91, the rack Ma. and the pinion movethe part X with the table 90 to the left, in, which movement all thebars 93 participate. They strip the spools 310. from their spindles andallow them to fall into the container 52, as shown in Fig. 19. The partX with the table 90 and the container 52 is then moved back. In thismovement the bars 93 take part until they strike against the holders ofthe spindles. The table-90 with the container 52 moves together with therack 4Ia, under the action of the pinion 45, farther to the right, intothe position shown in Fig. 20, whereby the tubes 31 are pushed on to thespindles. In this position the lever 91 is moved back so that the hooklevers 96 engage behind the pins 94 (Figs. 1'7 and 18). When this hastaken place the part X, with the containers 52, moves back into theposition shown in Fig. 17, so that the process of spooling can beresumed. Instead of providing a bar 93 for each spindle there may beonly two bars for one group of spindles, the two bars being connected at38 by a cross bar common to the group of spindles, the cross bar havingfor each spindle a recess 38 for stripping off the finished spool.

In the example shown in Figs. 17 to 20 there is, it is true, somereduction of accessibility to the thread, but this is not of anyimportance, having regard to the-compact construction of the cophandling device; in any case, however, it is the simplest form ofconstruction of the cop handling device X.

Figs. 21 and 22 show in somewhat more detailed form the actuatingmechanism for the cop handling device. The cranks 40a and 40b 70 arepivoted on their shafts Ma, 4"), and are coupled with each other, forexample by tie rods The cranks are provided with rollers 39a and 76 39b,by which they engage under the longitudinal walls 34a, 34b. Thelongitudinal movement of the cop handling device X is limited by stops5011 on bar 4811, for which the guide slot 49 (see Figs. 1, 3, 5, etc.,)is provided in the front wall 35a.

In Fig. 21 the mechanism is in its lower position at which time thespindles execute the winding operation. By rotating the hand lever 42and giving a quarter turn of the crank arms 40a and 40b in the directionof the arrow (1, the part X is raised to the position shown in brokendash lines, and at the same time it is moved to the extent of half thepitch of the spindles, so that the notches 38 engage the spindles behindthe cop spools. This unitary arrangement of the lever mechanism causesboth a vertical and a lengthwise movement of the part X to be producedby a single actuation of the lever mechanism.

By a partial return movement of the lever 42 the part X is first movedback lengthwise, so that the previously distributed tubes are disposedin front of the spindles in preparation for their mounting upon thespindles in the manner described above.

Fig. 22 shows how, instead of the cranks 40a, 40b, cams 98 may be used,having exactly the same effect. In this case the cams on the shaft llbare moved by those on the shaft Ma, through the medium of a rod 43.

Owing to the fact that the troughs 52 and also the conveyor 99, performat least the movement in the direction of the spindles with the part X,the trough and the conveyor are not only always held in the rightposition to receive the cops, but both parts, during'the working of themachine, are pushed inwards under the spindles. If the trough and theconveyor'were stationary, as hitherto, then the trough and the conveyorwould have to be in a position which would considerably widen themachine.

As already stated with reference to Figs. 11-14, the trough 52 forreceiving the spools may be provided at its bottom with a conveyor bywhich the spools are conveyed to a collector. In order, however, thatthe conveyance of the spools to the collector and their distribution inthe latter should take place in a proper and regular way, the conveyor,consisting for example of an endless band 99, is provided as shown inFigs. 23-25 with cross bars I09, between which the cops are placed. Themovement of the conveyor band is, as already mentioned, produced byrollers 99a, one of which is driven by any suitable means. For conveyingthe spools to the collector H, the device X may be provided with a feedpipe or feed channel H0, as shown in Figs. 23 and 24. The collector ismoved to and fro mechanically under the channel H0, by means-of rackgear Illa andacam disc lllb.

Fig. 25 shows another example of this device, according to which thecontainer Ill is stationary while the feed channel H0 is provided with ahopper and is swung to and fro above the container III, by the agency ofthe cam disc Illb,
